A thick and glossy layer of top coat over your nails. (possibly holo)
This term has been created by the queen of holosexuals Cristine (aka Simply Nailogical on Youtube)
Everything gets better with a little bit of glossy taco on top.
Cristine from the YouTube channel Simply Nailogical's way of saying "glossy top coat".
Cristine: " I suppose you don't have to put on a final coat of glossy taco. You could leave it--a little--textured. But you know me girl, I'm all about that glossy taco hahaha "
